 *	@abstract	Obtains a registration dictionary, filled out to the best of
 *	 GrowlApplicationBridge's knowledge.
 *	@discussion	This function creates a registration dictionary as best
 *	 GrowlApplicationBridge knows how.
 *
 *	 First, GrowlApplicationBridge examines the Growl delegate (if there is
 *	 one) and gets the registration dictionary from that. If no such dictionary
 *	 was obtained, GrowlApplicationBridge looks in your application's main
 *	 bundle for an auto-discoverable registration dictionary file. If that
 *	 doesn't exist either, this function returns <code>NULL</code>.
 *
 *	 Second, GrowlApplicationBridge calls
 *	 <code>Growl_CreateRegistrationDictionaryByFillingInDictionary</code> with
 *	 whatever dictionary was obtained. The result of that function is the
 *	 result of this function.
 *
 *	 GrowlApplicationBridge uses this function when you call
 *	 <code>Growl_SetDelegate</code>, or when you call
 *	 <code>Growl_RegisterWithDictionary</code> with <code>NULL</code>.
 *
 *	 This function was introduced in Growl.framework 0.7.
 *	@result	A registration dictionary.
